Re: Java on AS400 Beginer Question

["David Morris" <David.Morris@xxxxxxxxxxxxx>]

Robert,

You would put your java code in the IFS. To compile start
Qshell using the QSH command (you should load Qshell
on your system if it is not there). In Qshell you would use
commands like cd, mkdir, ls, and javac.

>From a green screen use QSH and pass your java
call in the command parameter. You may need to
set your CLASSPATH using ADDENVVAR first.

You have a few options on the call. The easiest, if you do
not need to pass data between the RPG program and Java
is to use QSH and pass your java xxxx command in the
command parameter using QCMDEXC.

Other options are to use a data queue or call your java
directly from RPG. If performance counts, a data queue
is a good bet because it bypasses the startup cost
of the JDK.

I have a very siple question I hope that somebody can anwser for me.

I have a java program that I currently run from a DOS prompt.  I want
to
more this program to the as400 and maybe put and rpg wrapper around
it.

Can I do this?

If so where do I place the Java code?

How do I compile?

How do I set a classpath?

Can I call this from a green screen command prompt? If so how?

Can I call this directly from an RPG ILE? If so how?

Sorry for the 20 questions but I think they should be fairly easy for
anybody who has already done this, I am not a newbie to Java or the
400, the
Java on the 400 so I don't expect it should be to hard to point me in
the
right direction.
